可用率下降要结合任务类型看，长任务比轻量聊天更难容忍波动。
This article is generated from RelayRank monitoring samples and common relay selection questions to provide a practical decision framework.
What to watch
Current risk-watch examples include doroai、easychat、OwlAI、dawapi、packycode、WorldBase.ai. These signals require repeated observation rather than one-sample conclusions.
Do not judge a relay by one metric. Availability, latency, status changes, model coverage, billing rules, and transparency should be read together.
Practical advice
After risk signals appear, reduce usage weight, keep a backup, and observe the next 24 to 72 hours.
Before long-term use, run small real-task tests and keep at least one backup endpoint.
